We're halfway through the NFL preseason, and now that we've seen all teams play two games with a good idea of the key players on their respective rosters, it's time to reload Sporting News' NFL Power Poll.

The mighty offenses of Green Bay and New England remain a strong 1-2 punch at the top, but from No. 3 through 32, there's quite a bit of reshuffling since the late July edition.

For this edition, we'll also check in on the rookies to watch for each team:

1. Green Bay Packers (previous rank: 1)

Rookie to watch: WR Randall Cobb.

It's just not fair that Green Bay drafted Cobb and gets tight end Jermichael Finley back healthy to add to Aaron Rodgers' loaded arsenal of receivers.

2. New England Patriots (2)

Rookie to watch: T Nate Solder

The first-round pick is proving he can hold his own as Tom Brady's blindside protector while Matt Light is ailing. Solder just might do enough to push for the starting gig soon.

3. Pittsburgh Steelers (4)

Rookie to watch: DE Cameron Heyward

The Steelers' three-man line doesn't get as much attention as the league's top linebacker crew, but Heyward looks like he will contribute well in the rotation behind Brett Keisel.

4. Atlanta Falcons (5)

Rookie to watch: WR Julio Jones.

The quartet of Matt Ryan, Roddy White, Michael Turner and Tony Gonzalez was an already impressive offensive-skill nucleus, but the speedy Jones provides new life.

5. Baltimore Ravens (7)

Rookies to watch: WRs Torrey Smith and Tandon Doss

The Ravens needed to get younger and faster at receiver to help Joe Flacco's progression, and expect Smith and Doss to join second-year TE Ed Dickson as key contributors.

6. New York Jets (3)

Rookie to watch: DE Muhammad Wilkerson

Rex Ryan knew he needed some youthful pop for his 3-4, there's hope Wilkerson can become a younger version of now former Jet Shaun Ellis.

7. Philadelphia Eagles (6)

Rookie to watch: LB Casey Matthews

Matthews has a lot on him to help the defense gel from middle linebacker, considering the big additions up front (Cullen Jenkins) and at cornerback, (Nnamdi Asomugha).

8. New Orleans Saints (8)

Rookie to watch: RB Mark Ingram

The Saints love having so many options at running back, and Ingram should further boost their red-zone production to complement everything Drew Brees does well in the area.

9. San Diego Chargers (11)

Rookie to watch: RB Jordan Todman

How does San Diego replace the versatile Darren Sproles in the offense and return game? With Todman and first-year player Bryan Walters, the team might have two answers.

10. Indianapolis Colts (9)

Rookie to watch: T Anthony Castonzo

We won't know until the regular season begins just how good Castonzo can be blocking in front of Peyton Manning, but they need his help on the line.
